To e255 whom t may concern:

Be it known that I,- FRANK A. LANE; a

Y citizen of the United States of America, and

vresident of Meudon, Charlton county, Misn souri .have invented a certain new and useful )im rovement 1n Pump-Couplmgs, of

'whicht -e following is acomplete specification.

vThe present invention relates to pumping devices, and. aims to provide an improved ormo attachment for pump whereby the same may be quickly and conveniently attached to barrels, tanks or the like for permitting the contents thereof to be ut into other receptacles.

Accordingly I have devised a simple and convenient form of coupling structure forv adapting the base of the pumpto be mount'1 ed in the barrel or tank-opening and permitting a suitable hose connection to beat-I tached to the' coupling -and passed down into the'contents of.. the barrel or other container.

. lit is also sought to devise .a construction of the character' described which will be adapted to have a portion'thereof made in diiierent sizes for Aada ting the structure to be associated with di or tank o enings.

With. tiese general objects iuview,4 the invention will, nowbe described -by refer ence to the accompanying drawing illustrating one form of construction which I have devised or embed ing .thel pro sed 'the' present improvement;

improvements., after -vwnlch' the nove features therein will befparticularly setl forth and claimed. v j Y ln the drawingf l Figure 1 .'.s a sectional elevation of a tank having a pump mounted thereon .andfprovided with a coupling structure` embodying Fig. 2 is an enlarged sectional detail view showing the coupling structure between the pumpand tank l" Fig. 3-is a similar sectional view illustraiing modified vform ofA construction; all( f the pump.

ferr-ing new to the said drawing in de' taili the same illustrates the improved form of coupling structure in relation to a tank :5 the head of which is provided with a threaded opening 6 for filling purposes as Well as for the attachment of the means for pumped erent sizesV of barrel- 4l is an inverted plan view of the in s discharging the contents ofthe tank. In

.thepresent case I provide a suitable form of an ed bushing 7 having an external thread or fitting the thread 1n the openingen 6, as illustrated 1n Figs.. 1, 2 and 3. In the preferred form of the construction, shown in Fig. 2, 1 provide the bushing 7 with an internal thread adapted for engagement with an external thread formed on thev up er y end of a hose coupling member 8. he

lower end of this coupling member 8 is u also provided with an externally lthrezuied portion 9 of relatively smaller diameter for the attachment of a hose 10 which is of i717) flexible form and of suitable length for extending to the bottom of the tank 5 wheren the hose is provided with a suitable ty'pe of4 5' .strainer element y12, as shown` in Fig. 1.

Intermediate its end thecoupling mem 75 ber 8 is provided with an enlarged Wrench-` collar vportion 14 adapted for wrenching purposes in screwing t gether, thereby bringing the collarAv portion 14 to abutting engagement with the 80 in Fig. 3 diilers fromzthe' foregoing only Vin that the bushing 7 is interiorly threaded for fittin the exterior .of the pump socket 16 instea of the exterior ofthe coupling 8, the Ilatter accordingl p nection witli'the bus ing' 7 The invention is particularly useful in providing for the convenient attachment of pumps to tanks or' the like'for the elevation of thecontents thereof by to receptacles occupying vso much vhigher a position as to For example,

the filling of the tanks of tractors1-and the like has always been somewhatdicult be- -1.10

cause @fthe elevation ofthe fuel tank and its inaccessible position, so that the operi? e Yparts 8 and 7toi for the purpose of allowin a suitable or conthe `structure shown v915 having no directconm0 the 'pump-action 105 render iti inconvenient to y. A fill the same by other means.

tion of filling the same is awkward and laborious to say the least. In making luse ot' the presentinvention, it is only necessary to apply the hose coupling 8 to the bushing T and insert the latter vinto the( threaded opening of the tank, and then attach the hase of the pump l5 to the upper endol the couplingr 8. The nozzle 19 of the puinp 15 is fitted with a suitable flexible hose 2() ol appropriate length for the defp'ired purpose, Fig. l. of the drawing showing' the free end of said hose 20 fitted. into the reeeptacle 2l. to be filled1 which in the contemplated use 0l. the invention may he the tuel tank ot the taetor. The filling,r ot the receptacle 2l is thus rendered. a, simple and easy operation, thetank 5 beiner located at any desired point Where the user may wish to niaintai-n a supplyhf the liquid tuel 'for tractor use. lfVhere'the threaded openings t5 of the tanks may vary to a certain extent in size, it may merelyI be necessary to make the hussliing- 7 in a few differentsizes as regards the outside diameter thereof for taking.)r care ot this range, of sizes of openings 6, the internat diameter of the bushing being maintained the same for fitting the same-size ot' couplings 8. A t

lt Will thus he apparent that l hare provided a simple and eilieieut coupling struc` `ture for fulfilling the desired object oi the invention, and while l have illustrated .rhat now appears to he the preferred construct ion tiieraot l desire to reserve the right to malte such changes as may Vi'airl)Y i'all within the sco )e of the appended elainis,

2. The combination with a vcontainer provided \\'ith a. threaded opening, a'hushing internally threaded to tit said opening, a hose coupling' threaded through said bushing,'and provided with an annular elumlder abutting against said bushing, and a pump haring its` hase portion formed with a threaded socket srren'ed onto the outer end otsaid coupling.
